I am unable to connect to the internet on my Desktop. My laptop connects perfectly, both wired and wireless.
The chap at O2 checked everything remotely and said it was probably my network card, and I should contact my computer manufacturer. How can I check, myself, to verify that the card is/is not working?

The PC is connected by ethernet cable to the router, which was supplied by O2. The router, which has no model number, is labled "O2 Wireless Box". I have tried changing the ethernet cable, and have tried all the router ethernet sockets in turn. The O2 chap tried a remote repair, which included pinging Google (timed out four times), updating firmware and reinstalling software from The supplied O2 disc. I have also disconnected the router from the mains, and left it for 30 minutes before trying again. All of the LEDs on the router are working correctly, and I can use the laptop wirelessly and with the ethernet cable which is normally connected to the PC. I have tried renewing the Desktop IP address, to no avail. The network card is listed as a VIA Compatable Fast Ethernet Adapter, which, according to the device manager, is "Working Properly". The device location is "PCI bus 0, device 18, function 0". I am guessing, but does PCI bus 0 mean it is on the MOBO and not actually a PCI card? If so, what is to be done?
The ethernet socket is grouped with the other motherboard sockets, so I assume it is on the MOBO. The yellow triangle is on the Local Area Connections icon in the Network Connection Folder.

I assume you have checked that it is set to connect to internet via lan in the internet options in control panel? If so you could try fitting a PCI network card click here You don't have to buy online but you should be able to get one for under £10 in your local PC shop.

On Saturday night I turned of the power to the router and disconnected the power supply. I also removed all other cables. I left the router for about 12 hours.
The following day I reinstalled the software on the O2 broadband disc. I followed the instructions to the letter, and broadband was enabled first try.
Eventually I managed to get the desktop and laptop established on a network.
Now all seems to be workin well. I do not know, however, what caused the problem in the first place.
